VILLIAM Il. AIlBAOI-I, OF MANSFIELD, OHIO, ASSIGNOR TO THE BARR CASH AND PACKAGE CARRIER COMPANY.

CASH-CARRIER.

SPECIFICATION forming part of Letters Patent No. 411,515, dated September 24, 11889.

Application filed May 14, 1889. Serial No. 310,721. (No model.)

To all whom it may concern.-

Be it known that I, VILLIAM Il. ALBACH, a citizen of the United States, residing at M ansiield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Cash-Carriers, of which the following is a specification.

My invention relates to that class of transmitting apparatus for store-service in which ro the carrier runs upon awire way or track, and more particularly, but not specifically, to that type wherein the carrier is impelled by the wedging action of two or more track-wires eitherI diverging or converging behind itsuch, for instance, as represented in Letters Patent No. 357,449, granted to Samuel XV. Barr on the 8th day of February, 1S8'7-and for the purpose of the ensuing' description I shall adopt and make reference to apparatus constructed upon the principle of that made the subject of said patent.

In the Barr device two Wires extend from station to station, one wire being shorter than the other and being iixed tothe ends of levers, one at each station, while the other wire is secured to the shanks of said levers under such arrangement that when one lever is vertical the other will be horizontal and the wires stretched taut between them and separated at the lever which is vertical, while converged and brought into close proximity at the lever which is horizontal. Buffers or bumpers are placed on the ends of each lever, so that when either is horizontal it may receive the shock of the carrier, Which has been driven toward it by the parting of the wires at the other end of the track. Such a construction requires means for the attachment of the buffer to the lever, and necessarily circumscribes the thickness of the buffer to that which will be selfsupporting from the base. I propose, insteadm of a buffer attached to the lever, to employ a section of rubber tubing having thick walls and a bore of about the diameter of the Wire track, that it may be slipped thereover, and of any appropriate length, thus causing the track-wire itself to provide the means of attachment of said buffer and of its support. I further propose, in order to obtain greater elasticity and to diminish the liability of breaking the wire at the exposed end of the buffer, to form the latter of two sections of tubing, both slipped upon the track-wire and connected by a coiled spring encircling said wire. Finally, I propose, in order to still further diminish the liability of breakage where two wires are employed, to mount said buffer upon that wire which is longest, or which has the greatest length from its point of attachment to the point where the carrier meets the 6o buffer, said wire being represented in the Barr system by the lower of the two tracks there shown.

ln the drawings, Figure lisa side elevation at one station of a cash-carrier apparatus embodying my invention, and Fig. 2 is a detail in top plan view.

A represents brackets or any suitable supports for the levers which operate and control the traclmvires, and a guys or braces for 7o said brackets. At the station er terminals of the line are levers B, pivoted each to one of said brackets, and having, respectively, catches l) to receive and retain the carrier as it reaches the station. The catches herein shown are each formed of a wire loop C sufficiently spaced between its arms to receive the upper part of the carrier D and drop over its sides, but provided at the outer end with a rubber tube d, slipped over the bend of the 8o loop to drop on the farther side of the carrier after it has come in contact with and compressed the buffer. Only one of the levers is shown, and that as horizontal; but the position of the other will be understood from said Barr patent-to wit, that it will at the time be in a vertical position. One wire E stretches taut between ears e, pivoted to the ends of said levers, and a second wire E eX- tends from an ear e', pivoted to the shank of 9o the horizontal lever, to a second ear pivoted to the shank of the upright lever, this latter wire being the lowest and necessarily the longest.

In the Barr patent, as I have stated, a

`buffer is shown as attached to the end of the This buffer necessarily proj ectedbut very lit- IOO tle beyond the end of the lever for want of a support, besides requiring special fastenings, and consequently being expensive. It could therefore offer but very little elasticity to meet the shock of the carrier sent at greatspeed against it, and as it met the carrier above the upper wire, and necessarily above both, the momentum of the lowest end of the carrier would carry the latter on, tipping it and bringing a violent wrench on the upper wire just in advance of the buffer, ultimately resulting in breaking the latter. To avoid these defects and to apply the resistance more nearly on a line with the wires, I construct the buer F of a length of rubber tubing having thick walls and a central bore of about the diameter of one of the track-wires, so that it may be slipped snugly thereover. This tubing, in case it is applied to the upper wire, will then rest at its base against the end of the lever, and will be sustained slightly by the wire, which it encircles and embraces and along which it may be made to extend to any distance necessary to obtain a perfect resisting medium. In prac tice, however, I deem it advisable to apply this buifer to the lower track-wire, or that one which in the Barr system is the longest, hecause this, having a greater length between its end and the point where the buffer necessarily meets the carrier, can yield or bend more graduallybeneath the shock or jar, and therefore is less liable to break; but, whether located on the upper or on the lower wire, this buffer will meet the carrier practically on a line drawn between the upper and lower wheels or trucks, and since it surrounds the wire in this position it will to a great extent prevent the tipping or wrenching action above advertcd to. When said buffer is located on the lower wire, I have found it desirable, not only for the purpose of forming the seat for the base of the buffer, but also for 4convenien ce and economy in repairing the track when broken, to make that part of the lower track extending from the buffer to the shank of the lever in the form of a wire link f, having a loop or clevis f at its advanced end, to which the end of the line-wire is attached, when the By this arrangement itis obvious that line-wire disconnected from the latter, and the buffer slipped off and applied to a new wire, which will then be attached to the clevis or to the link upon which it is formed.

Although I have thus far spoken of the buffer as being composed of a length of rubber tubing slipped over the track-wire, and although I consider such a feature of my invention when applied to the lower track-wire, I deem it preferable to form this buer in sections g g', and interpose between the two a coiled spring g2, encircling the track-wire. By thus doing I obtain all the advantages of both the rubber and the metallic spring, the noiselessness of the first, with its sluggish elasticity and comparative stiffness, and the great compressibility, quick elasticity, and flexibility of the latter. The coiled spring may have coils of a diameter slightly less than the rubber tubing and be secured over the sections of the latter; or they may be considerably less in diameter than the tubing and the end of the latter be-formed of less diameter than thel bodyT part, as in Fig. l, and shouldered, so as to receive the ends of the spring, and with its shoulders form a seat for the same. This compound buffer, it will be observed, permits great iexibility to the line-wire or to the trackwire, so that it will readily bend or yield when I wrenched by the tipping of the carrier as it strikes the buffer, and thus avoid one of the chief causes of breakage. It also yields to a much greater extent than a buffer of rubber alone and much quicker, therefore distributing the strain of the shock and preventing it from coming always at one place on the wire, which also would speedily result in breakage.

I claime l. The combination, substantially as hereinbcfore set forth, with the lower or longer wire in a` cash-carrier apparatus of the nature described, and with the operating-lever, of a v buffer composed of a tube of rubber slipped over said wire.

2. The combination, substantially as hereinbefore set forth, of the operating-lever, the

i wire loop attached to the shank thereof, the

lower track-wire secured to said loop, and the tubular buffer seated against the loop. enlargement caused by the coiling of the wire 3. The buffer herein described, composed of two sections of rubber tubing connected by an intermediate coiled spring which clasps the ends of said sections.
